After scouring the plans for the Death Star, General Jan Dodonna discovered that a small, exposed, thermal exhaust port led directly to the massive battle station's reactor core. The small exhaust port was only two meters wide, meaning a small starfighter would be able to attack the vulnerable exhaust port. Luke Skywalker expressed that this mission was not impossible, explaining the he used to bulls-eye womp rats in his T-16 back home, which were not much bigger than two meters. Skywalker eventually succeeded in firing a proton torpedo into the exhaust port and destroying the battle station during the Battle of Yavin.
